Buzzing sound from automatic door lock on 1995 Honda Accord

Whenever I lock the doors, there is a loud buzzing sound. It started out as clicking noise before it became a buzz. Do the locks need to be replaced?

Take off the door panel and just disconnect the actuator. Then just use the lock on that door manually. You will save hundreds of dollars and it only takes ten minutes to fix..
Sounds like a possible lock motor actuator.
